On the image of Hitchin morphism for algebraic surfaces: The case $GL_{n}$

Lei Song, Hao Sun

The Hitchin morphism is a map from the moduli space of Higgs bundles $M_{X}$ to the Hitchin base $B_{X}$ , where $X$ is a smooth projective variety. When $X$ has dim…

Curves contracted by the Gauss map

Lei Song

Given a singular projective variety in some projective space, we characterize the smooth curves contracted by the Gauss map in terms of normal bundles. As a consequence, we show th…
